10. Partial Replacement of Aggregates Using Agricultural Waste in Concrete Manufacturing

The environmental waste management practices are picking up across the world day by day. The present work deals with scientific disposal of the Agriculture waste material (rice straws) by utilizing them as coarse aggregate in conventional concrete mix. In order to reduce the alarmingly adverse effects of this waste material on the environment, it has become utmost necessary to get rid of it wisely so that the disposal may not affect the environment. The incorporation of this solid wastes in M15 grade concrete mix as partial replacements to coarse aggregate is found to yield an alternative lightweight eco-friendly concrete. The compressive strength of rice straws reinforced concrete sample with 10% replacement found out to be 10.2 N/mm² which is 68% as compared to conventional concrete i.e., M15 (15 N/mm²). This waste utilization cum management practice makes the possibility of embedding the agriculture waste material into concrete, providing us a good sustainable, economical and lightweight alternative environment friendly construction material.
